Question

我正在尝试将变量传递给sql脚本并使用c＃运行。

我收到错误说

“缺少表达”。

fromDate和toDate以'dd // mm // yy格式传递。我没有使用OracleCommand同时传递参数吗？

public void TransactionReport(string fromDate, string toDate)
        {
            string query = "select s.store_code,count(i.invc_sid) as count from invoice_v i Left join store_v s ON i.sbs_no = s.sbs_no and i.store_no = s.store_no Where(i.created_date between to_date(@fromDate,'MM//DD//YY') and to_date(@toDate,'MM//DD//YY'))  and i.proc_status not in ('131072','65536','147456', '81920') and i.invc_type = 0 AND i.sbs_no = 6  GROUP BY  s.store_code";
            conn.Open();
            using (OracleCommand cmd = new OracleCommand(query, conn))
            {
                cmd.Parameters.Add(new OracleParameter("fromDate", fromDate));
                cmd.Parameters.Add(new OracleParameter("toDate", toDate));
                OracleDataReader dr = cmd.ExecuteReader();

尝试使用:代替@

string query = "select s.store_code,count(i.invc_sid) as count from invoice_v i Left join store_v s ON i.sbs_no = s.sbs_no and i.store_no = s.store_no Where(i.created_date between to_date(:fromDate,'MM//DD//YY') and to_date(:toDate,'MM//DD//YY'))  and i.proc_status not in ('131072','65536','147456', '81920') and i.invc_type = 0 AND i.sbs_no = 6  GROUP BY  s.store_code";

在Oracle中你不应该使用sign @，这只是在SQL Server中，只删除@，它会起作用...
